The base 100 is formed with a base-side uneven portion 110, and the pressing body 200 is formed with a pressing-body-side uneven portion 210, respectively. A gap G is formed between the base-side uneven portion 110 and the pressing body-side uneven portion 210 at least in a state in which the two are most separated, and the base-side uneven portion 110 and the pressing body-side uneven portion 210 , and when the pressing body 200 is pressed against the base 100, they are engaged with each other.

This creasing tool 1000 has a shape similar to a so-called office punch. A hole punch punches two holes in a piece of paper, but the wrinkle forming tool 1000 according to the present invention does not punch holes, but forms wrinkles in the piece of paper.

As shown in FIG. 4 and the like, the base 100 constituting the wrinkle forming tool 1000 has a rectangular shape in plan view, and a pair of base-side protruding pieces 120 protrude obliquely upward from both ends of one long side. formed. The base-side protruding piece 120 corresponds to a pressing-body-side protruding piece 220 of the pressing body 200, which will be described later, and serves as a hinge-connecting portion. Therefore, the base-side protruding piece 120 is provided with a base-side hole 121 into which the rivet 300 that serves as the center point of the movement of the pressing body 200 is fitted.
On the inner side surfaces of the pair of base-side protruding pieces 120, base-side elastic body recesses 122 are formed in which elastic bodies 400, which will be described later, are fitted. The base-side elastic body recess 122 is formed by integrating a base-side coil recess 122A into which the coil portion of the elastic body 400 is fitted and a base-side arm recess 122B into which the arm of the elastic body 400 is fitted. is formed in

Further, the base 100 is made of a synthetic resin having translucency, and has a lens portion 130 that is raised in a substantially semicylindrical shape. This lens part 130 is adapted to magnify what exists on the lower side of the base 100 .
The vertical dimension of the lens portion 130 is set to about 40 mm so that one column (about 33 mm) of a newspaper can be accommodated, and the horizontal dimension is set to about 120 mm to cover 20 to 30 lines. Needless to say, the dimensions of the lens portion 130 are an example and do not limit the present invention.

Furthermore, between the pair of base-side projecting pieces 120 of the base 100, a base-side uneven portion 110 is formed. The base-side concave-convex portion 110 includes two parallel concave grooves 111A each having a substantially V-shaped cross section formed along the long side of the base 100 and formed parallel to the two concave grooves 111A. It also has a single protruding vein 111B having an inverted V shape when viewed in cross section. One convex vein 111B is positioned between two concave grooves 111A and the lens portion 130. As shown in FIG.

Further, as shown in FIGS. 1 and 4B, an arrow 150 as a symbol is formed on the base 100 to indicate the direction in which the piece of paper is inserted.
It should be noted that the symbol is not limited to the arrow 150 nor is it limited to being formed on the base 100 . That is, the symbol may be formed on the pressing body 200 or may be formed on both the base 100 and the pressing body 200 .
Further, the portion where the arrow 150 is formed is formed so as to protrude outward from the base-side protruding piece 120 in order to facilitate insertion of the paper piece P. As shown in FIG.

On the other hand, as shown in FIG. 5, the pressing body 200 combined with the base 100 has a pair of pressing body side protruding pieces 220 projecting from both ends of one long side, so that the overall shape is rectangular in plan view. formed.

The two convex veins 211A are fitted into the two concave grooves 111A of the base 100. As shown in FIG.

The base 100 and the pressing body 200 configured in this manner are connected by a rivet 300 inserted through the base side hole 121 and the pressing body side hole 221 . Moreover, the rivet 300 is fitted in the coil portion of the elastic body 400 which is a torsion coil spring, and the arms of the torsion coil spring are connected to the recess 122B for the base side arm of the base 100 and the recess 122B for the pressing body side arm of the pressing body 200. 222B.
Therefore, the pressing body 200 is always elastically biased in the direction away from the base 100 .

A gap G is formed between the base 100 and the pressing body 200, which are hinged via the rivet 300, due to the resilient biasing force of the elastic body 400 when no external force is applied to the pressing body 200. (see FIG. 7). This gap G is a portion into which a piece of paper such as newspaper is inserted. Therefore, the gap G is set to a dimension that allows insertion of at least a general number of newspaper pages.
As shown in FIGS. 2 and 6, a piece of paper such as newspaper to be wrinkled is inserted into the gap G between the base 100 and the pressing body 200 from the side where the lens portion 130 is not provided. It has become.

As shown in FIGS. 2, 6 and 7, after inserting the corners of the stacked pieces of paper P from the gap G, the pressing body 200 is pushed toward the base 100 while resisting the elastic body 400 .
As a result, the paper piece P sandwiched between the base 100 and the pressing body 200 is formed with unevenness, ie wrinkles, by the base-side uneven part 110 and the pressing body-side uneven part 210 . These are two grooves 111A having a substantially V-shaped cross section and one ridge 111B having an inverted V-shaped cross section of the base-side concave-convex portion 110, and two convex veins of the pressing-body-side concave-convex portion 210. 211A meshes like a gear.

As shown in FIG. 3, the wrinkles formed in this manner allow the paper pieces P to be rolled up in a separated state without bunching them up, so that the paper pieces P can be easily rolled up.
When such wrinkles are formed, it becomes easy to turn over the piece of paper P without moistening the fingers with saliva or using a finger sack, so that hygiene and convenience can be enhanced.

Further, since the wrinkle forming tool 1000 is provided with the lens portion 130, characters and the like can be enlarged by placing the wrinkle forming tool 1000 on newspaper or the like. This makes the wrinkle former 1000 very convenient for those with impaired vision.
In the above description, the lens portion 130 is raised in a substantially semicylindrical shape, but it is needless to say that the lens portion 130 is not limited to this and may be another type of lens such as a Fresnel lens. Absent.

Furthermore, in the above-described embodiment, the base-side uneven portion 110 has the groove 111A and the protrusion 111B, and the pressing body-side uneven portion 210 has the protrusion 211A. 211A can also be uneven like a sawtooth.
